As organizations grow and evolve, they must implement technology changes to accommodate evolving infrastructure needs, often within complex systems running business-critical applications. Along with this, there frequently is an increased demand to reduce the costs of technology by sharing hardware and software resources, a demand many companies try to meet by establishing virtual environments. Virtualization balances the often underutilized physical machines by consolidating them into a single physical host that runs multiple Virtual Machines (VMs) sharing the four core resources—CPU, memory, disks and network cards—of one physical host.
